To a-ZZ whom it may concer-n.'

Beit known that we, MILTON C. STERN and HERBERT E. NETH, citizens of theUnited States, residing at Dayton, in the countyof h/Iontgomery andState of Ohio, have invented certain new and useful Improvements inAutographic Registers, vof which the following is a specification,reference being had therein to the accompanying drawing.

Our invention relates to autographic registers and in particular to arewind core therefor. v n

Theobject of our invention is to provide a rewind corewor cylinder forrewi'nding a strip of paper constitutingthe Vpermanent record retainedin an autographic register.

It will be understood that this rewinding cylinder must have the paperattached v`to, it permanently so that it will not slip and so thatduring the winding operation *the` paper will be positivelywound tightlyand uniformly and without tearing. This necessitates a irm even gripupon the Paperv1t is also an object of our invention to lpermit of theattachment of the paper to the 'rewind corek easily and effectively asheretofore it has been difiicult todo.

It isa further object of our invention' to .provide an easy meansy offorming the roll so wound from the rewind core. Heretofore it hasbeen avery difficult matter to detach the paper so rewound after it had oncebeen wound into a tight roll in the register.

It is a further object of our invention to provide an association withthe rewind roll and adjustable tension devi-ce so that as the tensionincreases due to the increasing size of the roll, means for-"adjustingthe pulley ofthe roll will be provided to maintain 'this tension at auniform point. f

. Referring to the drawings: u

Fig.y 7' is a Similar View of another `form of gripper bar actuator.`

Fig. 8 is a section showing'tlie pin engaging withV the stub axle.v

Referring to the drawingsin detail,y 1y is a rewind roll, the coreusually made of wood. This core has a passageway extending therethroughconsisting of a rcenter pas-` sageway 2 and endpassageways'and V4 oflarger diameter. The passageways'3`has an enlarged portion near the endas. at 5Ik for the reception of the actuator sprii'ig.`

Located in the passageway 3 is' a stubaxle retaining 7 known as theactuator axle. This axle is pinned into the roll 1 by the pin 8 `whichis located transversely thereof.

This aXle 7 is surrounded near its outer endv by the spring 6 oneend-`of which abuts against the end of the passagewayV 5 inthe roll 1and theother end against the'actuator disc 9. This disc is eitherprovided with a knurled margin 1() or studsy 11 to' facilitate thefingers of the operator enga'gingwith thedisc and rotating y'it' onv theaXle. This disc is provided with 'a slot 12 inv which there travels theend 13 of the gripper finger bar 14. The disc 9 is prevented" frommoving outwardly on the aXle due tothe action on the spring 6 bya-washer4 15- which is also mounted on the` a-Xler and held in positionby a collar 16 pinned to theaXle .by the pin 17. 1

The gripper bar 14 carriesl a plurality of yspaced vfingers designated18. The bar itself woundl upon the roll the fingers 1S maybeprojected'by the rotation of the disc andthe papergfirmlyengaged withthev rollsothat it cannot slip -or tear.

As the roll increases in size due to the fact that it is being` rotatedfor` the winding of the paper in the usual manner of autographicregisters, it becomes necessary to compensate for the additional strainbeing put upon the paper and it becomes necessary to relieve thisstrain. For this purpose there is provided the `following mechanism.Another stub axle 21 has one end mounted in the passageway 2 and itsouter end in the passageway et within the roll 1. A transverse pin 22pins the axle to the roll. The portion of the axle mounted in theenlarged passageway 4 carried a collar 23 as the abutment for a helicalspring 24 which surrounds this portion in the stub axle 2l. rlhe otherend of this spring abuts against a steel disc 25 which is carried on theaxle 2l adjacent the end of the roll 1. A pin 26 prevents this disc fromrotating as the pin is mounted both in the disc and in the roll 1.

Also mounted on the axle adjacent to the disc 25 in succession is afiber disc 2T, a steel driving gear 28, a liber disc 29, and a steeldisc 30. The steel disc 30 is provided with a collar 31 which is pinnedto the axle 21 by the pin 32.

It will thus be seen that the gear 28 which is loosely mounted on theaxle or shaft 21 will provide the entire clutch assembly and roll untilthe resistance becomes sufficient to cause it to slip with respect tothe roll and the clutch members 25, 27, 29, and 30, providing a means ofrelief for successive strain upon the paper being wound.

iVe do not desire to limit ourselves to the particular details ashereinbefore described, but comprehend within our invention a suitablemodification thereof for its practice.

Having thus fully described our invention,

what we claim as new and desire to secure by Letters Patent, is: l. In arewind roll, a cylinder for supporting the paper, a groove thereincommunieating with the exterior thereof, a gripper finger bar pivotedthereon below the surface of the roll in said groove, a plurality ofgripper fingers mounted on said bar, an axle supporting said roll, anactuator disc mounted on said axle engaging with one end of the gripperbar and adapted upon being` rotated to vary the ngers on the gripper barwith respect to the roll.

2. In a rewind roll, a cylinder for supporting the paper, a groovetherein coxnmunicating with the exterior thereof, a gripper finger barpivoted thereon below the surface of the roll in said groove, aplurality of gripper fingers mounted on said bar, an axle supportingsaid roll, an actuator disc mounted on said axle engaging with one endof the gripper bar and adapted upon being rotated to vary the fingers onthe gripper bar with respect to the roll, and yielding means toyieldingly resist the rotation of the' disc on the axle relative to theroll.'

In a rewind roll, a cylinder for supporting the paper, a groove thereincommunicating with the exterior thereof, a gripper linger bar pivotedthereon below the surface of the roll in said groove, a plurality ofgripper lingers mounted on said bar, an axle supporting said roll, anactuator disc mounted on said axle engaging with one end of the gripperbar and adapted upon being rotated vto vary the lingers on the gripperbar with respect to the roll, yielding means to yieldingly resist therotation of the disc on the axle relative to the roll, and means on saiddisc for engaging the fingers of the operator.

5. In a rewind roll, a paper supporting body, a passageway therethrough,a stub axle mounted in either end of said passageway, and means forpreventing the rotation of said axle in the roll, a groove in thesurface of said roll, a gripper bar pivoted therein carrying a pluralityof gripping fingers adapted to be retreated below the surface of theroll in its inoperative position and projecting above the position ofthe roll with paper wound thereon in its operative position.

6.
